The atacontrol utility is a control program that provides the user access
and control to the FreeBSD ata(4) subsystem.
The atacontrol utility can cause severe system crashes and loss of data
if used improperly. Please exercise caution when using this command!
The channel argument is the number of the ATA channel on which to oper-
ate. The following commands are supported:
attach Attach an ATA channel. Devices on the channel are probed and
attached as is done on boot.
detach Detach an ATA channel. Devices on the channel are removed from
the kernel, and all outstanding transfers etc. are returned back
to the system marked as failed.
reinit Reinitialize an ATA channel. Both devices on the channel are
reset and initialized to the parameters the ATA driver has
stored internally. Devices that have gone bad and no longer
respond to the probe, or devices that have physically been
removed, are removed from the kernel. Likewise are devices that
show up during a reset, probed and attached.
create Create a type ATA RAID. The Type can be RAID0 (stripe), RAID1
(mirror), RAID0+1 or SPAN (JBOD). In case the RAID has a RAID0
component the interleave must be specified in number of sectors.
The RAID will be created of the individual disks named disk0...diskN.
Although the ATA driver allows for creating an ATA RAID on disks
with any controller, there are restrictions. It is only possible
to boot on an array if its either located on a "real" ATA RAID
controller like the Promise or Highpoint controllers, or if the
RAID declared is of RAID1 or SPAN type, in case of a SPAN the
partition to boot must reside on the first disk in the SPAN.
delete Deletes a RAID array on a RAID capable ATA controller.
rebuild Rebuild a RAID1 array on a RAID capable ATA controller.
status Get the status of an ATA RAID.
mode Without the two mode arguments the current transfer modes of
both devices are printed. If the mode arguments are given, the
ATA driver is asked to change the transfer modes to those given.
The ATA driver will reject modes that is not supported by the
hardware. Modes are given like ``PIO3'', ``udma2'',
``udma100'', case does not matter. If one of the devices mode
should not be changed, use a nonexisting mode as argument (i.e.
``XXX''), and the mode will remain unchanged.
info Show info about the attached devices on the channel. The device
name and manufacture/version strings are shown.
cap Show detailed info about the device on channeldevice where
device is 0 for master and 1 for slave.
enclosure
Show detailed info about the enclosure on channeldevice where
device is 0 for master and 1 for slave. Fan RPM speed, enclo-
sure temperature, 5V and 12V levels are shown.
list Show info about all attached devices on all active controllers.
